Letters Patent No. 96,956, dated November I6, 1869.

IMPROVEMENT IN HANGING LOWER TOP-SAIL YARDS.

The Schedule referred to in these Letters Patent and 'making part of the same.

To all whom t't may concern'.-

Be it known that I, E. J PINKHAM, of Portland, county of Cumberland, and State of Maine, have invented a new and useful Improved Method of Hanging Lower Top-Sail Yards; and I hereby declare the following to bea full, clear, and exact description of the same, which will enable others to make and use my invention, reference being had to the accompanying drawings, forming part of this specification, in which- Fgure 1 is a side elevation of a portion of a mast, with my improvement thereon.

Figure 2 shows a different arrangement of the same device shown in lig. l.

Figure 3 is a detail of the metal cap and collar.

Sanne letters show like parts.

My invention refers to a method of so hanging the lower top-sail yard of vessels, that it can swing without wearing the mast, and will also be held in its proper position even after the top-mast may have been taken down from its position.

In the accompanying drawingsb, the lower mast.

c, the top-mast.

c,4 the lower top-sail yard. This is intended to be represented suspended by a metal support or crane, f, which is connected to a ring, g, slipping easily around on the mast. These I d0 not claim.

To the upper part ot' the lower mast bthere is litted, at 7:., the clamp t', encompassing the top of said lower mast as at h, and also, in the form of a ring or circle, the top-mast, as at j. 4

The form of the metal clamp and ring is best seen in lig. 3, where it is detailed and shown in top plan.

On the lower edge of this ring j, I construct a. shoulder, lip, or projection, k.

Upon this shoulder the lower edge ,of the ring g rests, which supports or helps support the weight of the yard. n

The square clamp t', around the upper part of the lower mast, is rigidly attached thereto, so that, the top-nnistbeing removed, the metal support ot' the ring g, that is, what is shown in fig. 3, will still remam.

Moreover, if the top-mast c be overtaken down, it is intended to slip easily through the circle j, leaving the lower top-sailyard all the time properly supporied in place. This is the particular purpose of' my invention'.

In the drawings the yard is represented suspended above the metal connection illustrated in fig. 3.

Some masters and othelsprefer to have the yard connected to the mast below t-he said metal connection. This can easily be done, as seen in iig. 2 at on, by a continuation of the metal connection, having either one or two shoulders, one at the top and the other at the bottom edge, as may be desired.

By the use of my invention, the yard is firmly and securely held in place, and still remains when the topmast is taken down.

That I claim as my invention, and desireto secure by Letters Patent, is-

The shoulder or lip k, applied as and for the purposes herein described.
